Feel like a pick-me-up? Choose one of the following to boost your brain function.

Chocolate: a powerful antioxidant as well as a vasodilator, which means more blood gets pumped to your brain. But make it dark, not milk.

Caffeine: your daily cuppa can help your concentration and focus, and will add to your bank of antioxidants.

Beans and legumes: an excellent source of folate, an important brain nutrient. People on antidepressants respond better to medication when they have an adequate supply of folate.

Nuts and seeds: a great source of vitamin E, associated with lower cognitive decline as you age. Walnuts and linseeds also contain Omega-3 fatty acids, known to enhance brain function.

Berries: great source of antioxidants.

Beetroot: high in natural nitrates that boost blood flow to the brain.

Eggs: a leading source of choline, a precursor to acetylcholine, which is a neurotransmitter involved in helping your memory.
